If P : Q = 7 : 4 and Q : R = 5 : 14, find (i) R : P (ii) P : Q : R.

Question

KnowledgeBoat · Accepted Answer

Given, P : Q = 7 : 4 Q : R = 5 : 14 To find R : P and P : Q : R, we will make Q same in both cases. Taking L.C.M of two values of Q i.e. 4 and 5 = 20 So, = 35 : 20 and = 20 : 56 Hence, R : P = 8 : 5. ∴ P : Q : R = 35 : 20 : 56 Hence, ratio of P : Q : R = 35 : 20 : 56.
